White Paper: Reverse Engineering
By: Dr. Thomas Read
Before expending the effort necessary to reverse engineer a device or object, it must be definite that the object under study is not covered by one or more patents. This avoids a dispute over patent violations. Once it has been established that no patent coverage exists, one can use multiple techniques to reverse engineer a product. These are summarized below:

Samples of Effective Product Warnings
The Goldhaber Warnings Report: In the last issue of this newsletter, I listed the major components found in most warnings along with making several suggestions that should help improve a warning’s conspicuousness and make it more likely to gain the attention of the product’s user at the time of use. The following is an example of a warning that

How to Design a Product Warning: Best Practices
The Goldhaber Warnings Report: In the last issue of this newsletter, I listed four key questions that must be answered when conducting a warnings review. Answers to these questions, as well as following the detailed steps I now provide, should help you determine whether or not you need to warn or, if you already warn, whether or not your warning(s) is/are adequate

Packaging and Product Liability
By: Sterling Anthony
A more appropriate term would be packaged product liability, because a packaged product consists of product + package, and either component (or both) can incur allegations of negligence, strict liability, and failure to warn
